President Donald Trump announced on his social media platform Truth Social that he will impose a one-year cap on credit card interest rates at 10%, effective Jan. 20, the one-year anniversary of his second inauguration. He cited affordability concerns and criticized rates of 20% to 30% under the prior administration.
This move represents yet another unprecedented government intrusion into the marketplace by his administration, potentially disrupting how banks price credit and manage risk. While aimed at easing consumer burdens, it raises questions about enforcement, as Trump provided no details on implementation — whether through executive action or congressional legislation. Banking groups quickly opposed it, warning of reduced credit availability.

Yet, with credit card issuers now in the crosshairs, should investors buy Visa (NYSE:V) and Mastercard (NYSE:MA), since they are merely payment processors and should not be covered by the edict?
Mounting Government Interventions Disrupt Markets
The Trump administration has pursued several policies that interfere with free market operations. These include imposing sweeping tariffs on imports, which have raised costs for businesses; taking stakes in several companies for national security or strategic industries; announcing steps to ban institutional investors from buying more single-family homes to address housing affordability; and now proposing a 10% cap on credit card interest rates, overriding market-driven pricing.
Over the past year, Trump has also taken other actions that shocked markets, often to their detriment. These include abrupt trade policy shifts and regulatory overhauls that increased volatility in sectors such as technology and manufacturing. Stock indices dipped multiple times in response to unexpected announcements.
Tracing the Rate Cap’s Potential Ripple Effects
Trump first floated the 10% cap idea during his 2024 campaign, promising a temporary limit to combat high rates. In 2025, Congress saw bills introduced to enact it, including S.381, the 10 Percent Credit Card Interest Rate Cap Act, introduced by Sen. Bernie Sanders, which temporarily caps rates at 10%. A similar House bill, H.R.1944, was introduced by Rep. Alexandria Ocasio-Cortez.
Statistics highlight the issue’s scale: 82% of Americans have credit cards, according to a Congressional Research Service report. At the end of last year’s third quarter, the Federal Reserve reported $1.23 trillion in credit card debt, up $24 billion from Q2.
The cap would primarily affect banks that issue cards, such as JPMorgan Chase (NYSE:JPM), Citigroup (NYSE:C), and Capital One Financial (NYSE:COF), by limiting their interest revenue. Visa and Mastercard, however, operate as payment networks that facilitate transactions, earning fees based on volume rather than interest. They do not issue cards or bear credit risk.
While the move could save consumers money on balances — potentially $100 billion annually, according to a Vanderbilt Law School analysis — it might alter behavior. Lower rates could encourage paying down debt, reducing outstanding balances and transaction volumes. Conversely, they might spur more usage, boosting spending and fees for networks like Visa and Mastercard.
Banks are likely to challenge the cap in court, arguing it harms credit access and violates market principles. Such litigation could delay or defeat implementation, as seen in past regulatory disputes. For Visa and Mastercard, this could be mixed: reduced credit availability might curb transactions short-term, hurting revenue, but if consumers spend more due to affordability, it could benefit them.
Overall, the impact on them appears limited, as their business models insulate them from direct interest rate effects.
Key Takeaway
This proposal does not strongly make Visa and Mastercard immediate buys, given uncertainties around enforcement and potential court delays. Reduced credit issuance could temporarily pressure transaction volumes.
However, since the cap is only for one year and rates would return to prior levels afterward — assuming no extension if results fall short — their long-term prospects remain solid. Visa and Mastercard have strong track records of paying and raising dividends, with Visa increasing payouts annually since 2008 and Mastercard since 2006. These make them reliable additions to portfolios focused on steady income and growth, regardless of short-term policy shifts.
